[0027] In the above-mentioned specific technical scheme, a positioning mechanism is provided, and the door shell 3 is placed on the support column 5, one short side of the door shell 3 contacts one end of the positioning plate 6, and then the positioning plate 6 at the other end is moved, and the two short sides of the door shell 3 are clamped by the positioning plates 6 at both ends, and then the movable seat 7 is moved toward the edge of the movable plate 4, so that the movable seat 7 cooperates with the support column 5 to fix the two long sides of the door shell 3, thereby realizing accurate horizontal positioning of the door shell 3. After the positioning is completed, the push block 8 moves toward the direction close to the door shell 3, and the flange portion 26 is bent 90° under the action of the push block 8. The device is easy to operate, and the door shell 3 is accurately positioned, thereby improving the quality of the product and the efficiency of processing.

[0028] The push block 8 is installed on a fixed plate 9, and the fixed plate 9 is connected to the output end of the telescopic cylinder 10. A guide plate 11 is provided on the side of the fixed plate 9 away from the telescopic cylinder 10, and a guide column 12 is provided on the guide plate 11. The guide column 12 is slidably connected to the telescopic plate 28, and the telescopic plate 28 is slidably connected to the push block 8. The guide plate 11 is connected to one end of the elastic telescopic rod 13, and the other end of the elastic telescopic rod 13 is connected to the telescopic plate 28.

[0029] In the above-mentioned specific technical scheme, the guide plate 11 is fixedly installed on the fixed plate 9, the guide column 12 is installed on the guide plate 11, the telescopic plate 28 is slidably connected to the guide column 12, the push block 8 is fixedly connected to the fixed plate 9, and the telescopic cylinder 10 is started. The telescopic cylinder 10 drives the telescopic plate 28 and the push block 8 to move toward the door shell 3. When the telescopic plate 28 contacts the door shell 3, the elastic telescopic rod 13 contracts, the telescopic plate 28 stops moving forward, and the push block 8 continues to move forward, thereby realizing the bending of the flange portion 26.

[0030] The movable seat 7 is connected to the output end of the movable cylinder 14, and the movable cylinder 14 is installed on the movable plate 4. When the movable cylinder 14 is started, the movable seat 7 drives the door shell 3 to move, and the movable seat 7 and the support column 5 are in conflict with the inner wall of the door shell 3, thereby realizing the positioning of the long side of the door shell 3.
